To insure the setting was applied run the command:Īt the same time, you can look at the new features with the command: The string country 00 indicates that I have not set any value and the default settings was applied. To find out which region is currently configured, run the command: Everything you need is already available in Kali Linux! The old guides tell to install additional packages, but currently this is not necessary. Next, I'll show the power increasing of Alfa AWUS052NH in Kali Linux. Note that for channels at 5 GHz they have different values (different list of allowed frequencies and powers). You can examine the full current database in pain text here.Ĭountries where allowed channels 1 through 13 on 30.0 dBm power are (for instance): To check capabilities of your wireless adapter issue the command:įor example, the following frequencies and power are allowed for the US: This is not an insoluble problem, but each model needs its own approach. In this case it is impossible to raise the power above 15.0 dBm, even to 20.0 dBm) ĭriver features, for example, some drivers ignore system settings. The physical inability of an adapter to operate at capacities greater than 20.0 dBm (for example, the wireless interface initially shows a power of 15.0 dBm while 20.0 dBm is allowed. In theory, the described method should work for many wireless cards, but in practice there are the following limitations: Set the increased power for the wireless adapter. Set the system-wide setting of the regulatory domain to the value, that matches to a country where the power is allowed to be 30.0 dBm There is also an accompanying database, in which are prescribed the permitted frequencies and the allowed power. Regulatory domains (or "regdomain") is the country in which this device is supposed to work. You can take advantage of this loophole (make your wireless thinks it is located in a country where 30.0 dBm is allowed) and raise its TX Power to a value of 30.0 dBm. But there are countries in which there is a limitation of 30.0 dBm. In most countries, a Wi-Fi signal power limit of 20.0 dBm is set. In some countries it is not allowed to use the frequencies of some Wi-Fi channels (for example, channels 12, 13 and 14 can not be used in the USA). In different countries, legislation and technical standards varies, including in relation to Wi-Fi. Moreover some models will not support these settings or wireless chip may state that it "can" transmit with higher power, but the device's manufacturer probably did not place the appropriate heat sink in order to accomplish this. The default TX-Power of wireless is set to 20 dBm but you can increase it with a little trick to 30 dBm but let me warn you first that it might be illegal in your country, so use it at your own risk. The current version of this guide is here: An easy way to increase TX Power for Wi-Fi in Kali Linux and BlackArch
